GEOLOGY OF MOOSE RIVER GOLD DISTRICT — WOODMAN. 83 



belt contains only five leads in this quarry, and the overlying 

 whin has thickened to nearly eight feet. The hanging wall 

 lead dips 40° N. on the north side of the quarry, and is thinning 

 out fast to a stringy film of quartz. Outside the whin cap on 

 the south the Ferguson is found, two inches thick where seen. 



Division Hi : south anticline. — The Dreadnaught is a four- 

 inch lead on the west, twelve inches wide eastward, breaking 

 up more or less into angulars, and enclosed by slate. The Dry 

 belt, sometimes called the Tripe belt, is a slate band seven to 

 •eight feet wide, with about a foot of angulars. The Moleskin 

 is a belt of two leads, three and four inches thick, with a whin 

 hanging wall. The Comstock, where opened on the east side of 

 the blockj is five to seven inches. South of it is a four-inch 

 lead. 



Division Hi : three trenches. — Three surface cuts have been 

 made in this block (pis. 7, 18). The attitude of the beds in them 

 has been stated in the earlier part of this paper. In trench No. 

 1 (pi. 7, fig. a) only the Jo. Taylor belt is exposed. A portion of 

 the foot- wall lead is figured in pi. 9, fig. c, to show the character 

 of its irregularity in the western part of the division. This lead 

 pitches east 10°, the hanging wall lead 5°. The latter is 

 very dark and ribbony ; the former is white and cellular, with 

 much iron rust. It is here two inches thick. Immediately 

 south of the whin overlying this belt, the Ferguson comes up 

 at the end of the trench, very much crenulated, and averaging 

 one and one-half to two inches thick. 



In trench No. 2 (pi. 7, fig. b) the first lead lies 32 feet south 

 of the north end, and is one inch thick, lying in a three-foot 

 belt of slate with a dip 72° N. Lead No. 2 is at 56 feet, two 

 inches thick, dipping 80° N. No. 3 is at 75 feet. It is a belt 

 of two, the north one two and one-half inches, the other a zone 

 of veinlets ; the two sets being six inches apart. It is probably 

 the Dry belt. "Whin lies on the hanging wall. No. 4 is at 79 

 feet, one-fourth inch thick, with a high north dip. No. 5 is a 

 belt of three, the north one 84 feet 4 inches south, the middle
